Buck Carapis
A praying mantis bugkin in an outback hat, chewing the stub of a cigar and carrying daggers. Buck wears the expression of someone who finds soft-skinned visitors more trouble than they're worth, but he helped the party get through the guarded eastern tunnel entrance by staging a loud, convincing argument with Roland Poland that drew the guards away.
Buck described the enemy creatures to the party: small, flight-capable, producing acidic secretions, showing no signs of intelligence or language. He's probably in jail now for his part in the distraction.
